If the running balance on your Société Générale statement does not add up row by row, that is exactly the kind of mismatch Convert·Into is built to catch rather than pass through silently. The engine reads the printed closing balance from the document and works through every transaction row, recomputing the running balance. Any row whose computed balance does not match the statement is isolated and flagged for review. The conversion never rejects an entire file because of a single mismatch: you receive the clean rows immediately, alongside a clear indicator of the line that needs attention.
Whichever order your Société Générale statement prints its columns in, each one still has to land in the right place once it reaches a spreadsheet. During export, each column from the extracted transaction table is mapped to the correct field in the output format. The date is placed in the date column, the description is routed to the memo field, and debit and credit amounts are assigned to separate columns so the totals reconcile without manual reordering. When you select Excel, CSV or QBO as the target, the layout is already arranged to match what a ledger or accounting package expects: no stitched-together text, no amount sitting in a note field where a formula cannot reach it, and no ambiguous sign conventions that would break an import.
